I’ve just acquired some in Southland. I’ll grow it up this season and can pass some root on to you in autumn/winter if you’d like? If you send me your email address, I can let you know when I harvest it.

I have plenty of horse radish, but I live in United States and I don’t know if I can send the roots over seas. If I can mail the roots I will. Does anyone know?

New Zealand has strict quarantine laws when it comes to importing fruit, herbs and vegetables.I am sure they would not let it come in.

Hi, I would love to plant horseradish in my Waihi garden. Is there anyone in the area who can spare a piece of root? Cheers, Vera

Found this site looking for where to put my horseradish and saw someone wanted echinacea. I have some.

Hi, I would love to find out where in the Hawkes Bay region I can buy a plant or cutting? Having grown up in Sweden / Europe with many traditional dishes containing the wonderfully hot root (grated and mixed in sauces, potato salads etc. .. the list is long) I truly miss the unique flavour ...
